Outside the Vancouver hotel where Cory Monteith's body was discovered, a makeshift memorial has been created as fans left flowers and notes commemorating the actor.
In the UK a Glee convention near Heathrow changed planned activities to allow fans to mourn the actor.
"The news was devastating," said Chloe Harvey, an 18-year-old fan from Portsmouth.
"No one had any idea what to say or do. It just shows how much of a truly amazing guy Cory was that everyone was so shocked and emotional about the news."
"We all woke up to hear the story, and no one really wanted to believe it was true," said Chloe-Louise Bond, a 22-year-old fan from Wakefield.
"Walking into the main room, you could just feel the tragedy in the air, absolute strangers became a family right in that moment. Everyone was crying and hugging and just trying to get over the shock."
